A candidate block description containing transactions, rules and header fields from which mining jobs are built.
Block template is best understood as part of a system rather than as an isolated definition. Its related coordinates show the mechanisms, incentives and historical records that give the term practical meaning.
Block template sits between protocol rules, economic incentives and software operated by independent participants. In Bitcoin, no component is authoritative by itself: miners propose history, fully validating nodes enforce validity, and users decide which rules and software they accept.
Understanding Block template helps distinguish a verifiable Bitcoin mechanism or historical record from slogans, products and market narratives.
For the clearest picture, read this entry together with getblocktemplate, Stratum V2, Coinbase transaction. The reverse links also lead from Stratum V2, Extra nonce, getblocktemplate, Job negotiation.
